Course overview
Disciplined problem solving and 8D is a systematic approach which focuses on the causes of problems as opposed to simply addressing their symptoms! The methodology is structured into eight disciplines (8Ds), emphasizing a cross-functional team synergy let by a qualified facilitator and the use of tried-and-tested quality tools and techniques.
By the end of this interactive course and workshop participants will understand the array of ‘disciplined’ problem solving tools (including ‘human factors’) and be able to facilitate and document value-adding problem-solving exercises using the Eight Disciplines (8D) in conformity with customer-specific requirements.
This course meets in full the training syllabus of AESQ RM13000:2023 (8D Problem Solving Method) and the requirements of ARP9136:2016 (Aerospace Series - Root Cause Analysis and Problem Solving [9S Methodology])
Assessment of learning is achieved through structured Team exercises and an aerospace Case Study. Our tutors provide feedback and advisement to ensure that risk-based thinking, ethical behaviour, human factors and associated best practices are fully understood in the context of the aerospace/defence industry.
All participants undertake an assessed Team Case Study to test their application of 8D
A optional 1½-hour written examination is available at the end of Day-2 based on an individual analysis of an Aerospace Case Study.
The 2-day course is highly interactive and uses Aerospace Case Studies and group exercises. The course timings are -
Day-1: 08:30 - 17:00 Focus: Disciplined Problem Solving Methodology and Tools
Day-2: 08:30 - 15:30 Focus: 8D (Eight Disciplines) explained with Case Study
Optional written exam and/or Team Case Study (all open book) - 15:30 -17:00
On-site coaching (option)
TEC also offer on-site coaching session delivered over 1- or 2-days as an option. We facilitate an 8D problem solving session with the organization’s Champion, Team Leader and designated team members.

Extended questions & answers
Who should attend
Champions/Sponsors, Facilitators and Team Leaders who must respond to customer requests for corrective action using the 8D process and communicate progress using the 8D Problem Solving Form of AS13000.
Particular emphasis is placed on empowering, as well as qualifying, the individuals who will be facilitating 8D workshops.
Apart from these nominated ‘Facilitators’ all persons participating in the cross-functional problem-solving team will benefit from attending this course.
This is a TEC "Practitioner" course – consequently it incorporates "train-the-trainer".
Deliverables & benefits
Students attending this course, and successfully undertaking the Quizzes and Exercises, will receive a training certificate containing the TEC Transnational Logo (recognised training provider).
The 8D problem solving methodology covers three key stages of correction and corrective action. This course empowers participants to -
Act rapidly to put immediate containment action in place to protect the customer (stop the bleeding!)
Find and fix the root cause with a permanent corrective action on all current product
Prevent the recurrence of the problem in the future by identifying and implementing preventive action anywhere possible within the organization
Organizations need to empower a Champion/Sponsor, Facilitator(s) and team members in the 8D problem solving methodology in line with the requirements of the AS13000 standard.
Organizations offering 8D problem solving embedded in their QMS will have a distinct competitive advantage.
TEC's 2-day course will empower and qualify all of the organization’s cross-functional team members to undertake value-adding 8D problem solving and communicate progress to the customer concerned using the 8D Problem Solving Form of AS13000.
The individuals attending will learn how to use a set of powerful quality tools for both data collection and analysis. In addition they will be able to plan and facilitate 8D problem solving exercises.
